IMPROVEMENT IN STREET LANTERNS.

Specification forming part of Letters Patent No. 121,327, dated November 28, 1871.

To all whom it may concern:

Be it known that I, ALoIs BURGER, ofthe city, county, and State of N ew York, have invented a new and useful Improvement in Street Lantern; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which drawing- Figure l is a vertical cross-section of my invention. Fig. 2 is a vertical cross-section taken at right angles to the plane of the cross-section, Fig. l, in the line .t of that figure.

Similar letters indicate corresponding parts.

This invention relates to an improvement in street lamps or lanterns, and it consists of a detachable frame united together by inside bars or rods said frame supporting and confining' in position a glass globe having the form of a truucated cone 5 and furthermore, it consists of a comhina-tion of parts, all of which will be hereinafter more fully described.

A designates my improved lantern, whose frame consists of an upper ring, B, provided with an interior cross-bar, C, extending from side to side of the ring. The depth or thickness of the cross-bar C is less than the width of the ring, and the cross-bar is arranged between the upper and lower edges of the ringso as to allow the ring to project both above and below the crossbar. The projecting part D of the ring below the cross-bar serves as a flange to confine the top of the glass globe. The outside of the ring B is provided with a projecting flange, E, which serves to strengthen the ring and protect the lantern and its glass globe. F designates a lower ring, also provided with a central cross-bar, C, which supports the bottom of the glass globe, and is arranged below the upper edge of the ring so as to leave a flange, G, above the cross-bar to receive the bottom of the glass globe within it. In this example the lower ring is of less diameter than the upper ring to conform to the shape of the globe, which is made in the form of an inverted truncated cone. The upper and lower rings B F are held together by means of bolts H H, two being the number here shown, which are passed through holes in the cross-bars, their heads bearing'against the outside of one cross-bar, while their ends, which are provided with screwthreads, are fastened by nuts I I on the outside of the other cross-bar. The screw ends of the bolts are provided with shoulders J J, which bear against the edges of the holes in the upper cross-bar, (see Fig.1,) through which they are passed, and so prevent them from drawing the rings B and F too close together and thereby injuring the globe of the lantern. The cross-bar of the lower ring is pierced with a hole, K, to receive a gas or other burner, and the lower ring may be formed in any suitable manner to allow the lantern to be attached or connected to any desired support or fixture, such as a post or bracket. The cover L` of the lantern is hinged at one side at M to the upper ring, and its other side is provided with a spring-catch, N, which is sprung over the outer flange E at a notch, l, in that ilange, so as to fasten the cover down. The lantern can be easily taken apart by raising the cover, when the bolts can be lowered and the globe and rings ofthe frame be released.

The glass globe of the lantern, by means of this invention, is fully exposed from the outside; and strength, neatness, and simplicity are combined in my lantern in a high degree.

What I claim as new, and desire to secure by Letters Patent, is-

The circular rings B F, anges D Gr, cross-bar C, globe O, and inside bolts H, in combination with the hinged cover L, spring catch N, and projecting flange E, all arranged and operating substantially as and for the purpose set forth.

This specification signed by me this lst day of August,` 1871.
